RECORDER FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 258,672, dated May 30,1882,

Application filed November 5, 1881. (No model.) Patented in France July6, 1880, No. 137,687, and June 25,1881; in BelgiumOctober 14, 1880, No.52,776, and August 2, 1881 in England (provisional patent) July 23,1881, and in Italy August 27, 1881.

To all whom it may concern:

Be it known that I, ALEXANDRE LOUIS POUGET, civil engineer, ofMontpellier, in the Republic of France, have invented certain new anduseful improvements in apparatus for registering the travel and periodsof rest of locomotives or other vehicles; and I do hereby declare thatthe followingis a tall, clear, and exact description of the same.

My improvements relate to mechanism for registering automatically thedistance traveled a forward or in backward direction, and the by alocomotive or other vehicle, whether in speeds at which such travel ortravels have been effected, as well as the periods of rest.

For the purpose of my invention, I make use of a sheet of paper or otherappropriate material, which I roll on a cylinder, and which is dividedlongitudinally as well as vertically by parallel lines. The size of thissheet and the distance apart of the lines thereon may vary according tocircumstances, as will be understood hereafter. F or the purpose ofrecording the work of a locomotive I find that a sheet twentycentimeters high and thirty long, giving an approximate diameter of tencentimeters when placed on the cylinder, answers every purpose. Thehorizontal lines thereon can be five millimeters apart and the verticallines one centimeter. Howcver,this paper is laid at a slight angle onthe cylinder in such a manner that the extremities of these lines at oneend of the sheet correspond with the extremities ofthe following lineson the other end of the sheet in such manner that they all form togetherone long continuous volute or screw, thepitch of which is fivemillimeters. I impart by means of clock-work rotary motion the cylinder,the speed being one revolution per half minute, and I cause it to rotateon a screw ot' five millimeters pitch, so that at each revolution itprogresses exactly five millimeters. I record the motion of a locomotiveor other vchicle on this sheet of paper by means-0t a set of punches ormarkers, preferably three, the first of which indicates fractions of akilometers, the second kilometers, and the third the retrograde motionof the vehicle, also in fractionsot' kilometers, and in kilometers, byunderlining the distance run over as recorded by the two first-mentionedpunches. I impart the requisite motion to these three markers by meansot'awheelrunningontherailofthelincoronone of the locomotive-wheels. Iconvert the rotation of this wheel for the first two mat kers into ato-and-fro motion by means of an eccentric and a ratchet-lever, whichimpart an intermitting motion to one or more disk-wheels in which areset studs that lifthammers. These latter, on falling, strike themarkers, and for the third marker (that records the retrograde .travel)I make use of a stud on the measuringwheel or on a disk attached to itsaxle, acting on ajointed lever constructed in such a manner that on theforward motion of the vehicle an arm on such lever is caused to rise andfall without actuating the lever, but on its backward or retrogrademotion it acts on a stop on such lever and strikes the hammer whichactuates this marker.

In order that my invention may be clearly understood, I will describethe same in detail conjointly with the three accompanying drawings, onwhich- Figure l isaplan of myimprovedapparatus, one-half size; Fig. 2, afront elevation of the same, onehalt' size, and Fig. 3 a full-sizerepresentation of the recordingshcets with a few registrations thereon.

In these Figs. 1 and 2, l is a clock-work of any appropriatedescription,indicating on the dial the usual time, and rotating thecylinder 2 one-half revolution per minute. This cylinder is fixed on atube, 4, which turns on atixed screw, 3, the pitch of which is fivemillimeters, and the cylinder is connected with the screw by a pin, 6,so that during its rotation it is compelled to advance live millimeterseach revolution, thus describing throughout its entire travel acontinuous volute or spiral corresponding exactly with the volute linesprinted on the paper. Afurther key, 5, fixed on the tube 41, allows ofthis longitudinal motion of the cylinder on the tube while the tube andcylinder are revolving. At the outer extremity of the screw there is acircular groove, 7, in which the pin 6 enters when the cylinder hasarrived at the end of its travel, and thereby it can rotate withoutprogressing. This pin 6 is mounted on a spring in such a manner that byraising the same the cylinder can be disengaged and set backward orforward to any direct point without being obliged to rotate it, andwhether the clock-work is going or not. 14 is the shaft on which theactuating road-wheel is set.

10 is the first punch or marker which records fractions of kilometers onthe sheet of paper, in this case twenty-five meters. It is struck by ahammer, S, which is raised successively by the four studs 23, set on oneface of a ratchet-u heel, 16, and which act on the lever 24, made faston the same spindle as the shaft of 8. This ratchet-wheel is fast on aspindle that rotates in the two plates 42 42 of the box containing themechanism for actuating the punches, being rotated intermittingly by theeccentric 15, the rod 17 of which is jointed at 19 on a ratchet lever,18, pivoted at 20, and provided with a ratchet, 21. 22 is aratchet-tooth pivoted on one of the plates 42, and which serves toretain the ratchet-wheel 16 after each impulsion. For the purpose, as inthis case, of marking the travel every twenty-five meters theratchet-wheel l6 wouldhave forty teeth. The road-wheel keyed on theshaft 14 (and not indicated in Figs. 1 and 2) would be about eightycentimeters in diameter, and the throw of the eccentric 15 such as toturn the ratchetwheel one tooth for each revolution of the road-wheel.12 is the second punch or marker which records the kilometers run. It isstruck by its hammer 13 by means of a stud, 27, projecting from one faceof the wheel 26, and which acts on a lever, 28, fast on the same spindleas the shaft of the hammer 13. The gear 26 is driven by a pinion, 25,which is made fast on the same spindleastheratchet-wheel16. It has onehundred teeth against the pinions ten. Consequently it makes but onerevolution against ten made by the ratchet-wheel, and thus while thislatter, by means of its four studs, marks every twenty-five meters runover, the former will mark or record one kilometer.

11 is the punch or marker which records the distances run over backward,by underlining the marks recorded for every twenty-five meters and onekilometer run, it being understood that such distances are recordedsuccessively, whether the spaces run over be ahead or retrograde. 9 isits hammer, and 40 its 1ever, hung below it, but on the same spindle asthe ham mer-shaft. This lever is actuated, when the locomotive isretrograding, (which direction is the reverse of the one indicated bythe arrow, Fig. 2,) by adoublelever, 33 34, made fast on a spindle, 39,and this requisite motion is imparted to the said lever by means of astud, 38, struck in the face of asmall disk fast on the mainactuating-spindle 14, which, actuating the extremity of a pawl, 36, hungon the end of the lever 33, drives both of them to the right. Theupperlever, 34, moves consequently to the left, whereby the lever 40 israised, and with it the hammer 9, and directly the pin 38 has passed thepawl 36, the spring 43 brings the hammer down on the said marker orpunch '11, aspring, 46, having simultaneously brought back levers 33 and34 to the position indicated in Fig. 2. 35 is an adjustable screw forlimiting the motion of the said compound lever 33 34. When thelocomotive is progressing forward, as indicated by the arrow, Fig. 2,these parts, 11, 9, 40, 43, 3t, 39, and 33, remain at rest, inconsequence of the stud 38, which is then traveling in the direction ofthe arrow, simply tilting the pawl 36 on its axis 37. A spring, 44,brings it back each time to its normal position. 41 is a guide for thepuuchers or markers 10 11 12. I propose replacing, when convenient, thepunches 10, 11, and 12, with their guide 41, by three springs on theouter extremity of which and on their under faces are fixed the markersindicating fractions of kilometers, kilometers, and the backward travelas above. \Vhen struck by their respective hammers S, 9, and 13 they aredepressed on the paper, and when liberated by their hammers theirelasticity raises them immediately a slight distance from the paper. In

-another caseIpropose to suppress the punches 10, 11, and 12 with theirguide 41 and the levers 24 28, and I place the punches where the hammersare shown. In such case the hammer-arms must be elastic, and the puncheswill be raised directly by their respective studs 23 and 27 acting on ashoulder adapted to each punch, so that they are raised slowly anddescend with a certain percussion on being liberated by the said Stilts. Or, again, I propose placing the respective punches on vertical barsworking in guides, and which shall he raised by pins acting onprojecting shoulders, as is the case in-stamping-mills.

The recording-paper is shown full size, Fig. 3. When rolled on thecylinder 2 its extremity K L coincides with the line M N, and the point-K is in a line with point It 011 line M N, in order to form onecontinuous spiral, as above described. The Roman figures on theleft-hand vertical column represent hours, and the ciphers arrangedhorizontally the minutes of each hour, thirty minutes on each line, thusrequiring two lines, and consequently two revolutions for each hour. Thecylinder rotates in the direction of the progression of the figures, andits progressive motion, due to the screw 3, is in the direction from Mto N. The marks are reproduced on the paper by the punches striking on aband of carbon paper rolled on a cylinder, 29, and maintained thereon byclaws 30. A small piece of this carbon paper projects from the entirelength of this cylinder directly under the line of punches, so that bytheir percussion they cause the carbon paper to leave a correspondingmark on the recording-sheet below, and the cylinder of carbon paper iscaused to progress with the cylinder 2 by being free to move along astation-v ary rod, 45, and by being connected with the cylinder 2 bymeans of a pin, 31, running in a circular groove, 32, cut on the outerend of the tube 4; or I arrive at the same result by makin g use of atransparent sheet of paper printed on one face, and by placing suchprinted face IIO IIS

downward on a carbon paper rolled on the cylinder 2. The upper face, onwhich the indications will be read from right to left,is exposed toview,aud is useful asacheck that the sheet has been set to time with theclock-work. When the recording impressions are thus marked on the underface the screw 3 must be left-handed.

The sheet Fig. 3 contains three examples of the recording effected by myimproved apparatus. Thus, in the first case, at the commencement of thethird column on the eighth horizontal hand, there are recorded twomarks, l, one above the other, two similar marks at the commencement ofthe fifth column on the same band, and between these two doubleindications nine single indications. The marks V are the record ofkilometers, and those 1 of hectometers (or one hundred meters) run over,for in this case, in order to render the record clearer, three out ofthe four studs 23 are supposed to be removed. Consequently the remainingstud strikes otfevery hectometer run over. The reading of this firstrecord indicates that the locomotive commenced running at thirty-twominutes past three, and during the next two minutes it ran over onekilometer, and that in the first minute it accomplished sevenhectometers, and in the second only three. As the whole distance isunderlined, it shows that the locomotive was running backward orretrogradin It then remained stationary seven minutes. In the secondcase, at forty-one minutes past three and during the following fiveminutes, thelocomotivc has run exactly one kilometer each minute. Duringthe following minute it went over five hectometers, gradually slackeningspeed, as indicated by the gradually-increased spaces between eachheotometer. During next two minutes the locomotive remained stationary.It started again at forty-nine minutes after three, or thereabout,within a few seconds. It ran over one kilometer six hundred meters in alittle over one minute and a half. Neither of these last two recordsbeing underlined shows that the locomotive was going forward.

It will be easily understood that by augmenting the number of studs 23on the ratchet-wheel, or by diminishing the diameter of theratchet-wheel or that of the recordingwheel on the shaft 14, or again byaugmenting the stroke of the eccentric 15, the fractions of a kilometerindicated will be diminished, as may be required, and that by employinga larger cylinder, 2, and corresponding reeordpaper, such fractions maybe separated to any required distance from one another.

On placing the cylinder 2, covered with its recording-sheet, on itsscrew 3 it is of course necessary tolix it so that its indications as totime correspond with the time shown on the dial of the clock-work 1,thus in the eX- ample above recorded the party in charge will havepreviously brought the part indicating thirty-two minutes after threeunder the punch striking the fractions ofkilometers, after which theapparatus may be closed or locked, only leaving the clock-face in view.

In order to render the record -sheet still more complete, I leave in thecase of my apparatus a small opening immediately on the line of travelof the markers, and following the same, through which I pass anyappropriate instrument for writing or otherwise noting on the sheet thestation at which the locomotive at the time being has stopped or isremaining stationary.

Having thus explained the nature of my invention, I claim 1. Thecombination of the stationary screw 3, the rotating cylinder 2, providedwith the keyway, the sliding key 6, and the rotating tube 4, )rovidedwith the feather 5, whereby a rotative and at the same time aprogressive motion is imparted to the cylinders, while at any time theprogressive motion may be arrested by raising the sliding key out of thescrew, and whereby when such disconnection is effected the cylinder canbe freely moved by hand longitudinally on the tube for the purpose ofsetting it at any particular point, when progressive motion can be againestablished by reinserting the key in the thread of the screw,substantially as described.

2. In a mechanism for marking the fractions of kilometers (or othermeasures of distance traveled by a locomotive) on a recording-sheet, thecombination, with the shaft 14, rotated by a road-wheel running on oneof the locomotivewheels, and provided with the eccentric 15, of theeccentric-rod 17, lever 18, pawl 21, ratchet-wheel 16, carrying studs23, lever 24, hammer 8, and punch or marker 10, substantially asdescribed.
